STripFET F7 devices use an enhanced trench-gate structure that lowers device on-state resistance while simultaneously reducing internal capacitances and gate charge to deliver faster and more power-efficient switching. These three devices bring these benefits to the automotive market, claiming the lowest RDS(on) x Area and turn-off energy (Eoff) parameters available in the automotive market.

The new devices incorporate an optimised Crss/Ciss capacitive ratio to minimise switching noise, which, together with appropriate diode reverse-recovery softness, decreases EMI/EMC emissions. This eliminates the need for external filtering circuitry. Use the devices, ST suggests, in DC/DC, DC/AC and resonant LC converters in hybrid and electric vehicles. All three devices are Automotive Qualified to AEC-Q101. The STH315N10F7-2 and STH315N10F7-6 are housed in H2PAK packages with low stray inductance and high current capability and the STP315N10F7 is housed in a standard TO-220 package.

STH315N10F7-2 and STH315N10F7-6 are priced at $3.80 and the STP315N10F7 at $3.50 (1,000).
